Focus at Four: Coffee causing cancer? A&M researchers call foul on Calif. law

Texas A&M researchers say a warning label for coffee now required in California is unnecessary.

A judge in California ordered coffee companies to display a cancer warning label because of a chemical produced during the roasting process called acrylamide.

Acrylamide is on a list of chemical compounds that California law now requires businesses to inform their consumers about.

However, scientists at the Texas A&M Center for Coffee Research and Education say it would take more than 40 cups a day--for 1,000 days--before reaching a concerning amount of acrylamide.

"Research has found that in mice, it has induced cancer, when it was applied in pure form so even as a part of a product blended with many other compounds," said Leo Lombardini, director of the Center for Coffee Research and Education. "But the application in mice was over a thousand times the ones that we find in coffee."

"It made it to the list because, yes, there has been a link, and somebody picked up the list and said, 'Coffee has this,' so they put the two together," Lombardini said.
